  "re-frame outputs warnings and errors via the API function `console` 
   which, by default, delegates to `js/console`'s default implementation for 
  `log, `error`, `warn` `debug` `group` `groupEnd`. But, using this function,
   you can override that behaviour with your own functions.

  Notes:
  
    - `:before` functions modify and return their `context` argument. Unless they 
      side effect, in which case, they'll perform the side effect and return
      `context` unchanged.
